University POSTGRES historical archive - postgr.esq mirror
==========================================================

Provenance
----------
Source:  https://dsf.berkeley.edu/postgres.html and subtrees
         (postgres-v4r2/, oldpost/)
Last upstream RCS edit: 1999-07-26 (committer: aoki @ Paul Aoki)
Mirrored on: 2026-05-21
Mirror operator: postgr.esq (greg@burd.me)

The University POSTGRES project (1986-1995) was the academic
predecessor to PostgreSQL. The work was led by Michael Stonebraker
at UC Berkeley with funding from DARPA, NSF, ARO, NASA, and
industrial sponsors. The Postgres95 successor (1994-1995, by
Andrew Yu and Jolly Chen) introduced the SQL frontend and is the
direct ancestor of every current PostgreSQL installation.

License posture
---------------
The University POSTGRES source tree is BSD-licensed; redistribution
is consistent with that license. Mailing-list archives and academic
papers are user-generated / authored content that UCB has hosted
publicly for ~30 years; mirroring is consistent with established
norms but not a license assertion.

Mirror policy
-------------
* Read-only mirror. We do not modify the original artifacts.
* Bit-perfect originals at https://postgr.esq/legacy/postgres-v4r2/
  and /legacy/oldpost/ exactly mirror the upstream tree.
* Original bytes are also preserved off-host in Cloudflare R2 at
  r2:pgesq/legacy-archive/ for redundancy.
* Extracted source trees under /legacy/extracted/ are added for
  browseability and offline grep; they are derivative.
* Academic papers under /legacy/papers/ include both the original
  PostScript and a ps2ascii text rendering for accessibility.
* Mail-archive at /legacy/mail-archive/ provides both the upstream
  monthly tarballs verbatim and an aggregated all-messages.mbox
  for grep/search.

Refresh cadence
---------------
Monthly via systemd timer (default disabled; operator enables
after a courtesy notification to dsf@berkeley.edu).
